I have googled this problem and have found very little help with it. I also had this trouble previously on my version of Eclipse Indigo. I have used both JRE 6 and JRE 7, and they have made little impact. Also, other updates and installers(such as the CheckStyle installer, the Oracle WebLogic Server Installer, and the Eclipse Updater) work just fine. How can I fix this? Thanks!
